Proteins are the workhorses of cells, adopting conformations that allow them to set off chemical reactions, send signals and transport materials. But when a scientist is designing a new drug, trying to visualize the processes ...

Zebrafish aren't just surrounded by liquid, but turn liquid—in part—during their development. As the zebrafish embryo develops from a ball of cells to a fully-formed fish, a region of the embryo switches its phase from ...

During embryonic development, the entire nervous system, the skin and the sensory organs emerge from a single sheet of cells known as the ectoderm. While there have been extensive studies of how this sheet forms all these ...

Tiny pores on the leaves of plants, called stomata, have a huge influence on the state of our planet. Through the stomata, plants absorb carbon dioxide, which is incorporated into carbohydrates, and release oxygen. But they ...
